I've been sitting a while as well. One day not long ago I figured out that I don't have a whole lot of "extra seasons" left. So now, it's what can I hit the ground running with in weeks or months, not years. And what is available that there are parts to fix it if it breaks or wears out instead of being a pile of useless junk. I can buy a nice, complete engine from someone, but if I can't easily get parts to fix it, it becomes junk when it breaks. I've just about finalized my solution. Just some details to work out.
